“…In this regard, such an NZEB would generate a large PV-surplus in summer, whereas in winter the energy demand has to be covered from the power grid (so-called winter gap). As a general rule, in multi storey buildings the available area for PV compared to the treated area is not sufficient to achieve the net zero balance even if the building is highly efficient [3,4,5,6].…”

By 2021, all new buildings in the European Union must be nearly zero-energy buildings in order to contribute to the achievement of the EU-CO2 neutrality by 2050. As the technical options to achieve highly-efficient building envelopes are available and well-known, there is no doubt that the most promising Heating Ventilation and Air Conditioning systems will include heat pumps and photovoltaic panels. However, there exist ongoing discussions on the optimal system layout and the integration of storage to achieve nZEB. In particular, there are some good arguments in favour of very low demand, while contrariwise also high flexibility is seen as an important feature to enable so-called grid-reactive operation of the building stock. Integration of onsite storage and its influence on the energy demand of the buildings and the corresponding electric load profile with focus on peak power is investigated.
